BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to vertically mountable semiconductordevice packages. More specifically, the present invention relates tominimally packaged semiconductor devices which are vertically attachedto a carrier substrate. Preferably, the present invention also relatesto user-upgradeable surface mount packages.

2. Background of Related Art

Vertical surface mount packages are known in the art. When compared withtraditional, horizontally mountable semiconductor device packages andhorizontally oriented multi-chip packages, many vertical surface mountpackages consume less area on a circuit board or other carrier substratethan a horizontally mounted package of the same size. Many verticalsurface mount packages may also have a superior ability to transfer heatthan conventional horizontally mountable semiconductor device packagesand horizontally oriented multi-chip packages. Thus, the semiconductorindustry is finding that vertical surface mount packages offeradvantages over their traditional, horizontally mountable counterparts.Various vertical surface mount packages are disclosed in U.S. Pat. Nos.Re. 34,794 (the “794 patent”), issued to Warren M. Farnworth on Nov. 22,1994; 5,444,304 (the “304 patent”), issued to Kouija Hara and Jun Tanabeon Aug. 22, 1995; 5,450,289, issued to Yooung D. Kweon and Min C. An onSep. 12, 1995; 5,451,815, issued to Norio Taniguchi et al. on Sep. 19,1995; 5,592,019, issued to Tetsuya Ueda et al. on Jan. 7, 1997; and5,635,760, issued to Toru Ishikawa on Jun. 3, 1997.

Some designs of vertical surface mount packages include wire bondedleads to operatively connect a semiconductor device to a circuit boardwhich tend to increase the inductance and decrease the overall speedwith which the device conducts electrical signals. The use of permanentwire bonds is necessary to electrically connect many such semiconductordevices to the circuit boards while the semiconductor devices aretypically adhesively attached to the circuit board to be supportedthereon, thereby preventing the vertical surface mount package frombeing readily user-upgradeable.

Electrical connections may also be made between many types of electronicdevices and a circuit board by means of sockets. For example, socketsare commonly employed to establish and maintain an electrical connectionbetween a mother board and a daughter board, such as a single in-linememory module (SIMM). Exemplary devices are found in the following U.S.Pat. Nos. 4,781,612, issued to Roger L. Thrush on Nov. 1, 1998;4,995,825, issued to Iosif Korsunsky et al. on Feb. 26, 1991; 5,209,675,issued to Iosif Korsunsky on May 11, 1993; 5,244,403, issued to GregoryJ. Smith et al. on Sep. 14, 1993; and 5,256,078, issued to Nai H. Lweeand David J. Dutkowsky on Oct. 26, 1993. Each of the foregoing patentsdiscloses the use of contacts within the socket which resiliently engagecontacts on the daughter board to establish an electrical connectionbetween the daughter board and the mother board.

However, none of those devices disclose the use of a socket forremovably mounting a minimally packaged semiconductor device to acircuit board. The circuitry of a daughter board and the typical use ofwire bonding to attach a semiconductor device thereto each tend toincrease the inductance of such devices.

Some socket-mountable daughter boards include more than onesemiconductor device permanently attached thereto. Thus, such devicesare not readily user-upgradeable.

What is needed is a low impedance, vertically mountable semiconductordevice package which has improved heat transferability and is readilyuser-upgradeable.

SUMMARY OF THE INVENTION

The vertically mountable semiconductor device assembly of the presentinvention includes a semiconductor device, a retainer which engages thesemiconductor device and a mounting element. The vertically mountablesemiconductor device assembly of the present invention also includes analignment device. The alignment device facilitates attachment of bondpads on the semiconductor device to their corresponding terminals on acarrier substrate.

The alignment device may include contacts to electrically connect a bondpad on the semiconductor device to a corresponding terminal on a carriersubstrate. Alternatively, the bond pads may directly contact theircorresponding terminals on a carrier substrate. Thus, as the mountingelement is attached to the alignment device, an electrical connection isestablished between the semiconductor device and the carrier substrate.

The mounting element may include two downwardly extending clips, whichflex outward during installation of the package onto the alignmentdevice. The clips spring back to their relaxed position as they engagerecessed areas of the alignment device. Removal of the verticallymountable semiconductor device package from the alignment devicerequires a slight outward flexion of the clips, such that they releasethe alignment device and may be moved upward relative thereto.

The present invention also includes a method of manufacturing thevertically mountable semiconductor device assembly and methods ofdesigning and fabricating a semiconductor device that is useful in thevertically mountable semiconductor device assembly of the presentinvention. A computer which includes the vertically mountablesemiconductor device package and assembly is also within the scope ofthe present invention.

Advantages of the present invention will become apparent to those ofordinary skill in the relevant art through a consideration of theappended drawings and the ensuing description.

DETAILED DESCRIPTION OF THE INVENTION

FIG. 1 shows a preferred embodiment of a vertically mountablesemiconductor device assembly 1 according to the present inventionincluding a semiconductor device package 10 and alignment device 40.Alignment device 40 is mountable to a carrier substrate 60 andestablishes electrical contact therewith. Vertically mountablesemiconductor device package 10 engages alignment device 40 tocommunicate electrically with carrier substrate 60.

With reference now to FIGS. 2 and 3, a first embodiment of verticallymountable semiconductor device package 10 includes a retainer 11 and asemiconductor device 12 attached to the retainer. Vertically mountablesemiconductor device package 10 also includes a mounting element 13,which extends downward from retainer 11.

Retainer 11 is an elongate member having a generally U-shapedcross-section with two substantially parallel arms 14 and 15, a joiningcomponent 16 disposed between the arms, and a receptacle 17 formed bythe arms and the joining component. Arms 14 and 15 are laterally spacedfrom one another a distance of R, which is slightly larger than thecross-sectional thickness of the semiconductor device 12 to be insertedtherein, referred to as distance D. Thus, semiconductor device 12 may beinserted into receptacle 17. Preferably, the difference between D and Ris sufficient to prevent damage to semiconductor device 12 during itsinsertion into receptacle 17, but small enough to create a sufficientlytight fit to restrict side-to-side movement of the semiconductor devicerelative to retainer 11.

In the present embodiment of vertically mountable semiconductor devicepackage 10, semiconductor device 12 is held within receptacle 17 by asecuring mechanism 18. Preferably, securing mechanism 18 holdssemiconductor device 12 within retainer 11 in a manner which maintainsthe semiconductor device's position relative to the retainer (i.e.,fixedly secures the semiconductor device within the retainer). Thus,securing mechanism 18 maintains the alignment of bond pads 19 a, 19 b,19 c, etc. relative to their corresponding contacts (reference character44 of FIGS. 8, 11 a and 11 b) in the alignment device during repeatedremoval and reinstallation of vertically mountable semiconductor devicepackage 10 relative to same.

Securing mechanism 18 includes an adhesive material, which holdssemiconductor device 12 permanently in place. A preferred adhesivematerial is compliant under stress, is an electrical insulator,withstands the high temperatures generated by the semiconductor deviceduring operation, does not tend to flow at high temperatures, and hasprimarily vapor degradative by-products. Such adhesive materialsinclude, but are not limited to, room temperature vulcanizing (RTV)silicones, other silicone gels, and other high melt pointthermoplastics. Other adhesives, such as epoxies, acrylics and others,are also useful in the present invention as securing mechanism 18. Otherembodiments of securing mechanism 18 are also useful in the retainer ofthe present invention, including, without limitation, an interferencefit between semiconductor device 12 and receptacle 17, a clippingmechanism within the receptacle, and others.

The length of receptacle 17 is approximately equal to the width ofsemiconductor device 12. Thus, as semiconductor device 12 is insertedinto receptacle 17, lateral movement of the semiconductor device isrestricted. With reference to FIG. 4, an alternative embodiment ofreceptacle 17′ may include an alignment mechanism 20′, which orients asemiconductor device 12 in a manner that aligns bond pads 19 a, 19 b, 19c, etc. relative to their corresponding contacts 44 (see FIG. 8) of thealignment device 40 (see FIG. 8). One configuration of alignmentmechanism 20′ includes one or more raised guides 21′ within receptacle17′, which direct the lateral orientation of semiconductor device 12relative to the receptacle.

Alternatively, referring again to FIGS. 2 and 3, during packaging,semiconductor device 12 may be laterally oriented within receptacle 17in such a manner that bond pads 19 a, 19 b, 19 c, etc. are positionedrelative to a center line of vertically mountable semiconductor devicepackage 10. Other alignment landmarks on vertically mountablesemiconductor device package 10, such as the sides of retainer 11 or thelocation of mounting element 13, may also be used to orient bond pads 19a, 19 b, 19 c, etc. relative to the remainder of the verticallymountable semiconductor device package in a manner which aligns the bondpads with their corresponding contacts.

Semiconductor device 12 is a semiconductor device of the type known andused in the industry. However, the bond pads 19 a, 19 b, 19 c, etc. ofsemiconductor device 12 are disposed proximal to a single edge 23thereof. Thus, during fabrication of semiconductor device 12, bond pads19 a, 19 b, 19 c, etc. are redirected to a location which is adjacent toedge 23. Methods and mechanisms which are known to those of ordinaryskill in the art are useful for manufacturing semiconductor deviceswhich are useful in the vertically mountable semiconductor devicepackage according to the present invention. Such methods include thefabrication of electrical traces which lead to edge 23 and thefabrication of bond pads 19 a, 19 b, 19 c, etc. adjacent to edge 23.Bond pads 19 may have a thickness that is greater than that of the bondpads of conventional semiconductor devices. Alternatively, bond pads 19may be fabricated from a mechanically durable, electrically conductivematerial. Preferably, the fabrication steps which precede thefabrication of the electrical traces that lead to bond pads 19 a, 19 b,19 c, etc. and the fabrication of the bond pads are unchanged from theirequivalent steps in the fabrication of prior art semiconductor devices.Thus, existing semiconductor designs are useful in the verticallymountable semiconductor device package of the present invention withlittle modification.

FIG. 5 illustrates an alternative embodiment of the semiconductor device12′, which includes bond pads 19 a′, 19 b′, 19 c′, etc. that aredisposed on an edge 23′. U.S. Pat. Nos. 5,266,833, issued to David F.Capps on Nov. 30, 1993, and 5,668,409, issued to Stephen Joseph Gaul onSep. 16, 1997, the disclosures of each of which are hereby incorporatedby reference, disclose processes for manufacturing such semiconductordevices.

Referring again to FIGS. 2 and 3, a preferred semiconductor device 12has a standardized number of bond pads 19 a, 19 b, 19 c, etc., which arespaced apart from one another at a standardized pitch, and which may bepositioned at a specific location relative to center line 22 ofvertically mountable semiconductor device package 10, or relative to anyother landmark on the vertically mountable semiconductor device package,such as a side thereof or mounting element 13. The placement of bondpads 19 a, 19 b, 19 c, etc. proximal to edge 23 imparts verticallymountable semiconductor device package 10 with reduced inductance as thebond pads are electrically connected to carrier substrate 60, relativeto many vertical surface mount packages and other packaged semiconductordevices in the prior art.

With continued reference to FIGS. 2 and 3, a first embodiment ofmounting element 13 includes clips 24 and 28, which extend downward fromopposite ends of retainer 11. Clips 24 and 28 each have a curvilinearshape, which includes a long straight member 25 and 29 having a firstend 26 and 30 and a second end 27 and 31, respectively. First end 26, 30rigidly attaches to retainer 11. The opposite, second end 27, 31 ofclips 24 and 28 is curved, and is also referred to as the alignmentdevice receiving end. Alignment device receiving end 27, 31 is curvedinward relative to vertically mountable semiconductor device package 10,such that it is adapted to engage a slot (reference characters 50 and 53of FIG. 7) of alignment device 40, described in further detail below.Preferably, clips 24 and 28 are continuous with one another and arejoined by a center element 32 which extends across retainer 11.

Clips 24 and 28 align semiconductor device 12 and its bond pads 19 a, 19b, 19 c, etc. vertically with respect to the alignment device (referencecharacter 40 of FIG. 1) (i.e., along the alignment device's z-axis).Thus, the preferred length of clips 24 and 28, and their orientationrelative to retainer 11, are dependent upon the height of semiconductordevice 12 and the location of bond pads 19 a, 19 b, 19 c, etc. relativeto edge 23.

Preferably, clips 24 and 28 are manufactured from a substantially rigidmaterial which has good thermal conductivity and which tends to reboundto its original shape following the release of a bending stress.Materials including, without limitation, metals, plastics (especiallyinjection moldable plastics), and fiber-reinforced composite materialsare useful for manufacturing clips 24 and 28. Metals, such as steel andaluminum, are preferred due to their rigidity and their shape retentionas load is placed thereon. Clip 24 and/or 28 may be employed as anelectrical ground or to protect semiconductor device 12 fromelectrostatic discharge.

Alternative embodiments of the mounting element, examples of which areillustrated in FIGS. 6 a and 6 b, are also within the scope of thepresent invention. Referring to FIG. 6 a, a second embodiment of themounting element 13′ is shown. Mounting element 13′ includes clips 24′and 28′ extending downwardly from the ends of vertically mountablesemiconductor device package 10′. Each of clips 24′ and 28′ includes aV-shaped alignment device receiving end 27′ and 31′, respectively.Alignment device receiving ends 27′ and 31′ are adapted to engage acorresponding engagement mechanism on the alignment device 40 (see FIG.1).

With reference to FIG. 6 b, a third embodiment of the mounting element13″ includes clips 24″ and 28″, which extend over major surfaces ofsemiconductor device 12. Each of clips 24″ and 28″ has an alignmentdevice receiving end 27″ (not shown) and 31″, respectively, which isadapted to engage a corresponding receiving mechanism on the alignmentdevice (shown in FIG. 9).

FIGS. 7 and 8 show an alignment device 40, which is an elongate memberincluding a body which defines an elongated interconnection receptacle41 formed in the top surface thereof and extending downwardly therein.Interconnection receptacle 41 has an upper end 42, which receives asemiconductor device 12 (see FIG. 1), and a lower end 43. Lower end 43includes contacts 44 therein. As alignment device 40 is mounted tocarrier substrate 60, the contacts are electrically connected to theircorresponding terminals 61 on carrier substrate 60.

Alignment device 40 is preferably fixedly attached to carrier substrate60. Mechanisms which are known in the art are useful for attachingalignment device 40 to carrier substrate 60. Such mechanisms include,without limitation, screws, protrusions which extend into or through thecarrier substrate, adhesives and solders.

FIG. 8 illustrates an embodiment of a contact 44, which includes aterminal contact end 45 and a bond pad contact end 46. Terminal contactend 45 is electrically connected with its respective terminal 61 bymethods which are known in the industry, including, without limitation,soldering, the use of Z-axis tape, and the use of an interference fit.Preferably, terminal contact end 45 of contact 44 is maintained in afixed position relative to terminal 61.

A spring arm 47, located between terminal contact end 45 and bond padcontact end 46, facilitates movement of the bond pad contact endrelative to the substrate contact end as a semiconductor device 12 (seeFIG. 1) is inserted into interconnection receptacle 41. Preferably,while subjected to a bending force, spring arm 47 exerts an oppositereactive (i.e., spring) force, such that bond pad contact end 46 snuglyabuts its corresponding bond pad 19 (see FIGS. 2 and 3). Thus, springarm 47 creates an interference contact between contact 44 and bond pad19 (see FIGS. 2 and 3).

Preferably, the end of bond pad contact end 46 is bent outwardly to forman outward extension 48. Outward extension 48 facilitates movement ofbond pad contact end 46 as a semiconductor device 12 (see FIG. 1) isinserted into interconnection receptacle 41. Preferably, the shape ofoutward extension 48 also prevents damage to semiconductor device 12during its insertion into interconnection receptacle 41.

Contacts 44 have a length of about 1½ mm (about 60 mils) or less. Morepreferably, contacts 44 are about 1 mm (about 40 mils) long or shorter.As those in the art are aware, longer contacts create greaterinductance. Thus, less parasitic inductance and capacitance aregenerated by shorter contacts 44. The total length of contacts 44depends on the thickness of the base of the alignment device, thecircuit length required to establish an electrical connection withterminal 61 on carrier substrate 60 (see FIG. 7), and the circuit lengthrequired to establish an electrical connection with bond pads 19 ofsemiconductor device 12 (see FIGS. 2 and 3).

Referring again to FIG. 7, a preferred embodiment of alignment device 40also includes a mounting element engager 49. A preferred mountingelement engager 49 includes two downward-facing slots 50 and 53 formedin opposite ends of alignment device 40. Sides align a semiconductordevice 12 (see FIG. 1) relative to the y-axis of alignment device 40. Inthe present embodiment, the ends of alignment device 40 align thesemiconductor device 12 relative to the alignment device's X-axis. Aswill become apparent, alternative embodiments of mounting elementengager 49 may be formed within interconnection receptacle 41, oncarrier substrate 60, through the carrier substrate, or elsewhere uponor in proximity to alignment device 40.

Mounting element engager 49 may include any other mechanism which willsupport the semiconductor device and align the semiconductor device withrespect to each of the alignment device's x-, y- and z-axes. FIG. 9illustrates an alignment device 40′ having a variation 49′ of themounting element engager, which is formed in the front 56′ and back 57′sides of alignment device 40′. Mounting element engager 49′ is adaptedto receive a corresponding mounting element 13″ of the verticallymountable semiconductor device package, such as clips 24″ and 28″,described above in reference to FIG. 6 b.

With reference to FIG. 10 a, a third embodiment of an alignment device40″ according to the present invention may include a plurality ofinterconnection receptacles 41 a″, 41 b″, 41 c″, etc. Thus, alignmentdevice 400 receives one or more vertically mountable semiconductordevice packages 10 (see FIG. 1).

FIG. 10 b illustrates a fourth embodiment of the alignment device 40″,wherein an interconnection receptacle 41″ opens to both the top andbottom surfaces thereof. Alignment device 40″ is useful with asemiconductor device having bond pads on the edge thereof, such as thatdisclosed above in reference to FIG. 5. Similarly, other embodiments ofalignment device 40″ are also contemplated to be useful in the assemblyof the present invention and, thus, within the scope of the presentinvention.

In an alternative embodiment of the alignment device 400, the mountingelement engager 401 may also include a semiconductor engagementmechanism. FIG. 10 c shows a preferred embodiment of such a mechanismwherein actuators 411 and 412 actuate corresponding engagement pins 413and 414 which engage the clips of the vertically mountable semiconductordevice package (not shown). As actuators 411 and 412 are moved towardthe center of alignment device 400, arms 417 and 418 are slid alongengagement slots 419 and 420 (not shown), retracting engagement pins 413and 414, respectively. While engagement pins 413 and 414 are retracted,the mounting element engager 401 is in a nonengagement state. Thus, thevertically mountable semiconductor device package may be lifted away anddisconnected from alignment device 400. Likewise, after the verticallymountable semiconductor device package has been installed on alignmentdevice 400, the movement of actuators 411 and 412 toward the ends of thealignment device causes engagement pins 413 and 414 to engage the clips,adjusting the mounting element engager 401 to an engagement state.Alternatively, the actuator may include a single button, which, whendepressed, actuates the retraction of engagement pins, hooks, tabs orany other component which engages the clips of the vertically mountablesemiconductor device package to adjust the mounting element engagerbetween an engagement state and a nonengagement state.

Referring to FIGS. 11 a and 11 b, as an example of the use of theassembly of the present invention, vertically mountable semiconductordevice package 10 is inserted into upper end 42 of interconnectionreceptacle 41. Clips 24 and 28 flex outward as they contact alignmentdevice 40. As vertically mountable semiconductor device package 10 ismoved downward relative to alignment device 40, alignment devicereceiving ends 27 and 31 of clips 24 and 28, respectively, engage theircorresponding slots 50 and 53 on the alignment device. Simultaneously,bond pads 19 a, 19 b, 19 c, etc. establish an electrical connection withtheir corresponding contacts 44 a, 44 b, 44 c, etc., respectively.Similarly, when the vertically mountable semiconductor device packageincludes a semiconductor device with bond pads exposed to the edgethereof, as described above in reference to FIGS. 5 and 10 b, as thevertically mountable semiconductor device package and alignment deviceinterconnect, bond pads 19 contact terminals 61 or a z-axis filmdisposed on the terminals to establish a direct electrical connectionwith the terminals.

FIG. 12 illustrates a computer 120 including a carrier substrate 122.Alignment device 40 attaches to carrier substrate 122. Verticallymountable semiconductor device package 10 is insertable into alignmentdevice 40, which establishes an electrical connection betweensemiconductor device 12 (see FIG. 1) and carrier substrate 122. Thus,with the attachment of vertically mountable semiconductor device package10 to carrier substrate 122, semiconductor device 12 is operativelyincorporated into computer 120.

The described embodiments of the present invention provide severaladvantages over devices in the prior art. The vertically mountablesemiconductor device package, which includes a mounting element and aretainer that only partially encloses the semiconductor device, isminimal and relatively simple when compared to many vertical surfacemount packages and other packaged semiconductor devices in the priorart. Consequently, materials and production costs are decreased. Whenused in connection with a convection-type air circulation system, suchas those that are known and used in the art, heat transfer away from thesemiconductor device is also improved over that of vertical surfacemount packages in the prior art and other traditionally packagedsemiconductor devices.

Advantageously, the vertically mountable semiconductor device package ofthe present invention is removably attachable to the alignment device.Thus, it is a consequent advantage that the vertically mountablesemiconductor device package of the present invention isuser-replaceable and user-upgradeable. Further, as the mounting elementengages the alignment device, the bond pads align with the mountingelement engagers.

Moreover, the bond pad placement and relatively short length of thecontacts impart the assembly of the present invention with very lowimpedance.

Although the foregoing description contains many specificities, theseshould not be construed as limiting the scope of the present invention,but merely as providing illustrations of some of the presently preferredembodiments.
